Battle for Wesnoth not responding with i3 window manager
 

I recently started using i3 and I really like it except for a couple issues. One of which is whenever I try to run Battle for Wesnoth, it doesn't respond to my mouse clicks. It doesn't matter if it's a floating window, tabbed mode, only thing open or with other programs; it doesn't respond. It does change what menu items are highlighted when I move the mouse, but I can't click any of them. It worked with other window managers so I don't know what's wrong here.

I had the same problem with fluxbox. I think I've read somewhere it's an SDL bug or something. I managed to run the game in KDE, though. Also, I noticed that if you click left and then right button in a fast sequence, it registers the mouse button event. The second time I run the game, it worked OK. I suspect it was the switching the game to fullscreen mode that did the trick.

I just tried it and the left-right trick worked here too, but switching to full screen didn't.

According to this site, downgrading the SDL libs should fix the problem
